Lodash _.words() Method

Lodash is a JavaScript library that works on the top of underscore.js. Lodash helps in working with arrays, strings, objects, numbers, etc.

The _.words() method is used to split the given string into an array of words. A pattern can be specified so that certain words can be removed from the string.

Syntax:

_.words( string, pattern )

Parameters: This method accepts two parameters as mentioned above and described below:

• string: It is the string that is to be split. The default value is an empty string.
• pattern: It is a pattern on the basis of which the words would be matched. It is an optional parameter.

Return Value: This method returns an array of words according to the pattern.

Example 1:

Javascript

// Defining Lodash variable
const _ = require('lodash');

// Specify the string to split
var str = "Geeks for Geeks";

// Using _.words() method
console.log(_.words(str));

Output:

[ 'Geeks', 'for', 'Geeks' ]

Example 2:

Javascript

// Defining Lodash variable
const _ = require('lodash');

// Specify the string to split
var str = "Geeks for Geeks";

// Using _.words() method
console.log(_.words(str, "for"));

Output:

[ 'for', index: 6, input: 'Geeks for Geeks', groups: undefined ]

Example 3:

Javascript

// Defining Lodash variable
const _ = require('lodash');

// Specify the string to split
var str = "& Geeks for Geeks &";

// Using _.words() method with
// a given pattern
console.log(_.words(str, /[^, ]+/g));

Output:

[ '&', 'Geeks', 'for', 'Geeks', '&' ]
